Hi,I have a friend in my dorm who knows a lot about hacking (at least relative to me). And he already once did ARP poisoning. So, since he is my friend I don't have that much to worry about but I am just wondering is there anything that I can do / download in order to make the computer safer?

ps. In the dorm there is an unsecured wifi available for all of us.pps. I have Windows 7.

The best thing to do always, even if you know there is nobody on your network. ALWAYS login with "https", most sites allow that.And by doing this, someone who's doing a Mitm-attack still doesn't know your login credentials.

are you connecting using the unsecured wifi or do you have the option to connect hardwired? The quickest and easiest way to protect yourself is to use a hardwired connection and slap a hardware firewall on it then connect to that either wired or wirelessly. not only would that improve your security but it would be hella faster bandwidth wise, with all those noobers connecting to the wifi.. downloading good pronz would be slow as balls. If you have to use the wifi, then ZoneAlarm could help, it's better than windows firewall... but you're on an open wifi so, is h@x0r paradise..

there are some other options but, it would require bringing you up to speed beyond what your tech level seems to be at this point.. and I can't do that in one post.

If you're running Windows, and you care in the slightest about your security and/or privacy, you should already have a firewall (hardware or software) plus an antivirus (I use Norton Internet Security). If you don't want to shell out for a paid firewall (torrenting it is extremely frustrating, as you need to regularly download the latest virus registries), Bullguard works well and is easy to use.

You really need to get a firewall and antivirus regardless of the network you are using f you're on the internet and running Windows.

Personally I'd say an antivirus isn't really necessary, as long as you possess come common sense, you probably won't run into many viruses. Personally, I'd say its not worth the money. And, if you're really suspicious about files, there are sites that you can upload them to, and they will scan it for you, probably not the best method for large files, but malware tend to be small applications as it is.

As was already suggested, use HTTPS as often as you can. Firewalls will certainly help, but like what was already said, an unsecured, open wi-fi is heaven for hackers.

To prevent and detect APR(A(dress Resolution Protocol) P(oison) R(outing)) the best approach is to use something like:Other approach is to use Wireshark.(To see all traffic send by/to you) Read the documentation and filter all packets so that wireshark only shows you ARP packets.
